To create child theme

If you don't want to modify the theme files everytime you update the theme, you have to create the child theme to modify the php code for this. You can find the tutorial about how to create the child theme here

Our theme wrap every function with if( !function_exists('some_function') ) command, so if you want to use any function, just declare it in the function.php file of the child theme and it'll overwrite the existing one.
